Another day, another step up the tennis ladder for Ana

One of the fastest rising stars in women's tennis continued her march to the top on Thursday, upsetting No.3 seed Vera Zvonareva, 62 64 in second round action at the J & S Cup in Warsaw.

Ivanovic, who picked up her first career Top 10 victory in her last outing at Miami - defeating Svetlana Kuznetsova, now has two Top 10 wins in her last two events after her straight sets victory over Zvonareva.

"I just tried to play my game, to attack her and get a little bit into the court and get her on the move and I think I did that pretty well," Ivanovic said. "I'm really happy the way it went today."

Ana will look for a spot in the semifinals on Friday when she faces No.6 seed Nathalie Dechy. Dechy moved into the final eight after recording a straight sets win against the Polish favorite, wild card Marta Domachowska, 64 76(4).
